Q:DN1800 can the length of ductile iron pipes be several meters? What is the total weight?
Ductile iron pipe is a kind of cast iron pipe.
Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?
Because of differences in depth and soil properties, the excavation width is differentUsually to ensure that the width of bottom surface on both sides of the 600 1400+ manual operation. (such a large pipe flange bolt, the tool is not easy to expand, so the need for manual operation. So wide)
Q:Some questions about the bearing capacity of nodular cast iron pipes!
The minimum tensile strength of ductile iron is 400MPa, and the stresses can be calculated according to the wall thickness, diameter and safety factor.
Q:How much is the installation fee of the 400 largest ductile iron pipe?
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc.. Water supply pipe is the first choice, with high cost performance.
Q:How can the ductile iron pipes be treated with corrosion protection?
Bituminous paint coatingBituminous paint coatings are pipes used to carry gas. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate drying
Q:What is a slide in type T flexible interface?
The disadvantage of the T type interface is the ability to prevent pipe slippage because the interface can not withstand axial forces, so the base of the line is positioned against the axial forceFigure slider type (type T) interface (TYT type)The T type interface utilizes the self sealing action of the rubber ring to preserve the tightness of the water, as shown in the following figure. The so-called self sealing action is that the rubber ring is subjected to fluid pressureFig. interface rubber sealWhen the actual contact pressure to form a rubber ring is equal to the contact pressure and the fluid pressure generated by the installation of pre compression on the rubber ring and the new contact pressure. Due to the contact pressure than the fluid pressure, so the interface has good sealing function.
Q:How to properly maintain FRP pipes
The wall of the pipe is smoothReduce flow resistance, increase flow speed and reduce energy consumption. Compared with the same size steel pipe, the flow rate of the same volume can be increased by about 10%, and no fouling and long-term use can not reduce the flow rate. The protection of cables in interference and heavy corrosion environment is better.
Q:Ductile iron pipe connection mode
Main points of installation: (1) clean the pipe mouth: clean all the sundries in the mouth. Second, clean aprons, aprons on the adhesive material on the apron: clean up, put the ring bending "plum blossom" or "8" shaped into a socket groove, and hand along the entire ring press again, or with a rubber hammer, to ensure that each part of the warping apron is not twisted, evenly the card in the slot.
Q:What is the relationship between the mechanical properties of spheroidal graphite cast iron and its spheroidization rate?
Poor balling and poor performance. Can do under tensile. General level three or four or more on it
Q:The difference between ductile iron pipe and UPVC drain pipe
Centrifugal ductile iron pipe is ideal for urban water supply, gas pipelines, sets of high strength, good ductility and corrosion resistance advantages, performance with nature, iron and steel, is the replacement of the traditional cast iron pipe and common steel pipe renewal;
